目的:比较Ⅰ类和Ⅱ类矢状骨面型成年男性舌骨位置的差异,探讨舌骨位置与矢状向骨面型的关系。方法:选择垂直向均角型的Ⅰ类和Ⅱ类矢状骨面型成年男性各30例,拍摄头颅侧位定位片,对其舌骨位置相关指标进行测量分析。结果:Ⅱ类矢状骨面型成年男性舌骨水平向测量指标除AH-Or外均小于Ⅰ类矢状骨面组,差异有统计学意义(P<0.05),但舌骨垂直向各测量值两组差异均无统计学意义(P>0.05)。结论:垂直向均角型的Ⅰ类和Ⅱ类矢状骨面型成年男性舌骨位置存在差异,Ⅱ类矢状骨面型成年男性舌骨位置比较居后位。 OBJECTIVE: To compare the hyoid position of adult male sagittal type Ⅰ and Ⅱ sagittal planes and to explore the relationship between hyoid position and sagittal plane type. Methods: Thirty patients of type Ⅰ and type Ⅱ sagittal osteoporosis were selected from each group. The skull lateral radiographs were taken and the related indexes of hyoid position were measured and analyzed. Results: The level of hyoid bone in adult sagittal bone type Ⅱ sagittal plane was lower than that of sagittal plane sagittal plane in AH-Or group (P <0.05) There was no significant difference between the two groups (P> 0.05). CONCLUSIONS: There are differences in the location of hyoidbones between adult vertical sagittal and vertical sagittal type Ⅰ sagittal slasms.
